What is the difference between ordinary organic fertilizer and bio organic fertilizer?

The production process of common organic fertilizer is as follows:
1. Raw material ratio per ton. Cattle manure 500kg + duck manure 300kg + mushroom residue 200kg + RW bacteria 100g. (the above cow manure and duck manure can be replaced by other livestock manure)
2. A pile of sticks. According to the above proportion of raw materials, according to the needs of the pile, the length of the pile is unlimited, the width is 2m, the height is 1m. In the stacking process, the materials should be stacked evenly layer by layer.
3. Add bacteria. Expand the volume of bacteria residue with the ratio of 1:5, mix evenly, and then sprinkle on the surface of the pile according to the number of the pile.
4. Stir fermentation. After the temperature is above 60 ℃, turn the pile every 4-5 days, ferment above 60 ℃ for 15 days, and then put the pile away.

5. Screening processing. After fermenting according to the above steps, it becomes pure organic fertilizer after screening and deep processing.
6. Granulation. The fermented pure organic fertilizer was granulated. According to the different raw materials, choose organic fertilizer granulator, disc granulator, roller extrusion granulator, stirring gear granulator, etc.
7. Drying, cooling, packaging. The moisture content of the newly made granules is relatively large, so it is necessary to dry the moisture to below 20% of the standard of organic fertilizer, and the dried granular organic fertilizer is directly packaged after cooling by the cooler.
After the organic fertilizer is produced according to the above steps, the organic fertilizer is stacked and fermented for the second time, and the temperature is reduced to about 40 ℃ after 15-20 days of stacking. The bacterial agent with the functions of phosphate solubilization, potassium solubilization, nitrogen fixation and underground pest control is evenly added into the fermented organic fertilizer in the proportion of 1:500. When the functional bacteria and fermented organic fertilizer were evenly added to the organic fertilizer in proportion, the standard of bio organic fertilizer could be reached after 7 days of fermentation. The other steps are the same as the production method of common organic fertilizer.
